On September 25, 1633, Katherine nein dan Gillechallum, a resident of Kintradewell in Caithness, was formally processed through the Scottish legal system under the case reference C/LA/3311. At a time when the legal framework surrounding the prosecution of witchcraft was intensifying across the Scottish Highlands and Lowlands, Katherine was brought before the authorities to answer charges brought against her. The historical record identifies her as a woman of Kintradewell, placing her within the specific socio-legal context of seventeenth-century Caithness, where local commissioners and ministers were increasingly active in pursuing allegations of diabolical pacts and maleficium.
Following the initial registration of her case, Katherine was moved toward trial under the designation T/LA/2100. This transition from the preliminary record to the judicial proceedings marks the procedural trajectory common to many accused individuals during this period, where evidence—often derived from local depositions—would be scrutinized by the relevant court. Although the specific nature of the accusations levied against her remains confined to the administrative documentation, the existence of both a case file and a subsequent trial record highlights the formalization of the proceedings directed at Katherine as she faced the gravity of the legal machinery then governing the northern shires.
